STOVEPIPE GUIDE.

Application filed November To all whom it may oncern:

Be it known that 1, JOHN MCDONALD, citizen of the Dominion of Canada,residing at Vancouver, in the Province of British Columbia, Canada, haveinvented certain new and useful Improvements in Stovepipe Guides, ofwhich the following is a specification.

This invention relates to a means provid ing easy entrance of one end ofa stove pipe into the adjacent end of another length. While it iscomparatively easy to connect adjacent lengths of stove pipe while theyare new, when the pipes, after having been used for some time, have beentaken down for cleaning, the operation gives a considerable amount oftrouble and the condition of the pipes is'not such that they can befreely handled.

The invention, which is the subjectof this application, provides aflared mouth ring which may be attached to the end of one pipe, whichring enables the end of the other length to be easily entered, andthereafter the mouth ring is readily removed.

In the drawings which accompany this application- Fig. 1 is aperspective view of the mouth ring, and

Fig. 2 shows in. vertical section its relation to the adjacent ends ofthe stove pipe lengths, the same being drawn apart.

The device comprises an open ring 2 of thin sheet metal, which is shapedto be slightly conical, and when the ends are brought together, thesmaller diameter of this ring is such as will readily pass within thelarger diameter 3 of one length of stove pipe, and the larger diameterof the ring such as will freely admit the smaller or crimped end 4 ofthe other length.

Atintervals apart around the outside of this ring 2 clips 5 are securedto it to project beyond the edge of the smaller end, and the projectingends of which clips are angled slightly away from the outer surface ofthe ring with sufficient space 6 between each clip and the ring topermit this edge of the ring to pass readily into the stove pipe withthe clips outside the same, see Fig. 2.

The two clips, which are near the open ends of the ring 2, and the oneon the opposite side of the band, are upwardly pro- 6, 1923. Serial No.673,150.

duced beyond the edge of the larger diameter of the band and areoutwardly turned as at 7 to form finger engagements.

In use, the edge of the smaller diameter of the ring 2 is passed withinthe end of the stove pipe having the full or larger diameter, with theclips 5 outside the pipe thickness. So placed the ring 2 forms a flaredmouthpiece through which the smaller or crimped end of the other pipemay be passed into the stove pipe end. After such insertion, the ring 2is readily withdrawn by the finger engagements 7 and removed fromconnection with the stove pipe.

This mouth ring 2 enables stove pipes to be readily connected together,even 211- though the ends may be distorted by continued use, and renderscomparatively easy, what is well known as an awkward and objectionablejob for the unfortunate on whom the work of taking down and cleaning thestove pipes devolves.

Having now particularly described my invention, I hereby declare thatwhat I claim as new and desire to be protected in by Letters Patent, is:

1. Means for inserting the end of one stove pipe into another, saidmeans comprising a ring having free ends, one edge of which ring isadapted for insertion into the end of one stove pipe while the otheredge is outwardly flared therefrom, clips secured at intervals apartaround the outside of the ring with a space between them and the ring,one end of each of said clips projecting beyond the edge of the smallerend of the ring.

2. Means for inserting the end of one stove pipe into another, saidmeans comprising a ring having free ends, one edge of which ring isadapted for insertion into the end of one stove pipe while the otheredge is outwardly flared therefrom, clips secured at intervals apartaround the outside of the ring with a space between them and the ring,one end of each of said clips projecting beyond the edge of the smallerend of the ring, and the opposite ends of certain of such clips beingproduced beyond the other edge of the ring and outwardly turned to formfinger engagements.

In testimony whereof I afiix my signature.

JOHN McDONALD.
